GLUE-APPLYING MACHINE FOR USE IN MAKING SPIRALLY-WOUND TUBES.

Original application filed June 28, 1909, Serial No. 504,915.

Specification of Letters Patent.

24, 1909. Serial No. 534,840.

To all whom it may concern:

Be it known that I, FRANCIS C. OSBORN, a citizen of the United States, residing at Detriot, in the county of Vayne and State of Michigan, have invented certain new and useful Improvements in Glue-Applying Machines for Use in Making spirally-Wound Tubes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to glue applying mechanisms adapted for use in that type of machines in which continuous strips or bands of paper are coiled spirally around the mandrel, cemented together, formed into continuous tubes, and are finally out 01f into predetermined lengths.

The subject matter of this invention constitutes a division from my prior application, Serial No. 504,915 filed June 28, 1909, and entitled, Machine for making spirally wound tubes.

The objects of the present invention are to improve the glue applying devices used in connection with this class of machine, and to this end the invention consists in the novel combination of parts and in the details of construction more fully hereinafter disclosed and particularly pointed out in the claim.

Referring .to the accompanying drawings forming a part of this application in which like numerals refer to like parts in all the views :Figure 1 is a plan view of so much of a tube winding machine as utilizes a glue applying device; Fig. 2, is an elevational view of the glue applying device detached from the machine shown in Fig. 1; and, Fig. 3, is a plan view of the parts shown in Fig. 2.

In order to make clear the use of the glue applying device the parts in Fig. 1 are briefly described as follows: 1 represents the base of the machine which may be similar to a lathe bed, and is preferably supported by suitable legs. On this bed are pivoted the bed pieces 3, and the swinging arm 4. To one end of the bed pieces is secured the usual slidable supports 7, which are provided with the screw adjusting means 15, for the purpose of adjusting the belts 12, which pass around the mandrel 23, and

serve to wind up the glued paper strips 25, into a continuous tube, all as is well known to those skilled in this art. The screw device 22 serves to adjust thebed pieces angularly with relation to the mandrel 23, and, therefore, to adjust the inclination of the belts 12, to said mandrel and to thereby control the pitch of the wound strips 25. 24 represents pipes which may carry steam into the mandrel 23. 21 is a pulley which may supply power to the shaft 17, and 18 represents a gear adapted. to transmit power to the drums around which the belts 12 are passed, while 26 represents a head in which the mandrel 23 is secured; 27 a cut away portion in said head; 28 securing devices for said head; and 45 represents suitable guides for the strips 25, all as fully set forth in my application above mentioned. In making paper tubes on this type of machine it is very desirable to evenly and uniformly coat the strips with a suitable adhesive, before they are fed to the mandrel and in Figs. 2 and 3 is shown an improved device for applying glue or other material to said strips as they come from the rolls in which they are wound. The rolls of paper 121, are provided wit-h rods or axles 122, which drop into slots or bearings 123, in the arms 124. It is very desirable to position these rolls with certainty and exactness, before the strips pass through the glue tanks, in order to be able to deliver evenly and smoothly the coated strips to the mandrel at a high speed, and, therefore, there is provided the broad bearings 126 near and in substantially the same horizontal plane as the bearings 123, which receive the rods 127, provided with the upright guides 125, adapted to embrace and position the roll 121, as shown. These rods 127, are adjustable and are held in the bearings 126, by the screws 128, taking against their flattened sides, as illustrated. By means of this adjustment, the uprights 125, may be so set as to embrace any width of roll, and to thereby prevent the paper from being at any time displaced in the roll. As illustrated, additional bearings 130, and 131 are provided to accommodate rolls of differentsize, and the said rolls are preferably supported from arms extending from the glue tank 132, which is provided with a glue roll 133, a hinged stripper 134, for the same, pivoted at 135,

a considerable distance from the stripping edge so that it may be swung some distance from the roll 133 to facilitate cleaning. The said stripper is also provided with set screws on each side to hold it in any desired position. An overflow pipe 137 is also attached to the tank 132, and this pipe, also, serves as a means to pass hot water into the reservior or space 138 beneath the tank, which protects the glue from burning. The pipe is cut away at the top, as shown, in order to facilitate the filling of the said space, and it extends out away from the glue, so that when the water boils in the reservoir and runs out of the pipe it will not spill into the glue. Normally, however, the gas is so regulated that the water will not boil over and this is accomplished by using an improved burner formed by combining two separate burners 139 and 140, one larger than the other and provided with separate valves for turning on the gas. Then the glue is to be heated up in the morning both burners are used, and when it is suliiciently hot, the larger of them is turned oft and the smaller one is regulated to keep the glue in proper condition. The guide rollers 141 and 142 are mounted respectively, between the centers 143 and 144, and the guide roller 145 is likewise mounted between the centers 146, and is provided with the scraper 147, as shown.

In operation, the rolls of paper 121 which are out by suitable machines from larger rolls, are mounted upon the rods 122 which latter are slipped into the bearings 123, whereupon the paper strip 25 is passed down under a suitable tightening device 25 and over the glue coated roll 133, under the guide roll 141, over the scraper 147, past the guide rolls 145 and 142, and then through the guides near the mandrel and around the mandrel, when they are caught by the belts 12 and formed at a rapid rate into a continuous spirally wound tube. As the rolls 121 differ in size the rods 122 may be supported either in the bearings 123 or in the bearings 130, so as to leave as little slack as possible between the said rolls and the glue coated roller 133. In addition to this uprights 125 firmly brace the flat sides of the roll and prevent it from Wabbling. The result is an even and uniformly coated strip of paper which at very high speeds is delivered to the mandrel with certainty and exactness, and is wound up into a perfectly formed tube at a very high speed indeed.

It is, of course, obvious that those skilled in the art may vary the details of construction and the arrangement of parts without departing from the spirit of my invention and, therefore, I do not wish to be limited to such features except as may be required by the claims.

What I claim is In an apparatus for applying adhesives to strips of material, the combination of means for mounting a roll of the strip, a tank for the adhesive, a water reservoir located beneath said adhesive tank, an adhesive applying roll mounted on the adhesive tank, a stripper associated with said adhesive applying roll, a tensioning device for the strip located adjacent said stripper, a pair of fixed guide rolls disposed to one side of the adhesive applying roll, a scraper located between said fixed guide roll, an adjustably mounted guide roll located above said fixed guide rolls, and burners located beneath the water reservoir, substantially as described.

In testimony whereof, I aitix my signature, in presence of two witnesses.

FRANCIS C. OSBORN.
